EXPERIMENTAL: +webkitAudioContext (Webkit Audio API) for getting waveform + eq/spectrum data in 360 visualizations, similar to Flash 9 API. Works only in Webkit/Chrome, NOT in Safari 6 (boourns) + iOS 6, apparently due to unimplemented (or I'm doing it wrong) createMediaElementSource() implementation. TBD.
Tweak 360 demos to allow Webkit Audio API spectrum/eq shiz, too
Merge branch 'master' into V2.97a.20120916+DEV+webkitAudioContext (renaming to match 20130101 release)
